- This inventionrelates to electric vaporizers of the typedescribed and shown 1n the earlier patents of Nicholas Lawner #1,625,034 and #1,663,558.

With vaporizers of this type the vapor passin out through the spout'and to be 1nhaled y the patient disperses in all directions and in order to prevent this the patient often has to use a towel or other means to be placed around the Ahead and hold it over the spout so that the vapors will be directed toward the mouth or nose of the patient. Such method is inconvenient and inasmuchas the vapors also strike other parts of the face and eyes of the patient the is rendered objectionable. j

It is, therefore one object of our lnvention to provide the electric vaporizer with means for deflecting the vapors so that thitag will be directed toward the nose and mou of the user andvrender the use of the vaporizer more effective and more comfortable Another obj ect is to so construct said means that the same can be conveniently moved into or adjusted to the position desired.

A still further ob'ect is to n rovide a construction which wil ermit t e positioning of the said vapor de ecting means so as to facilitate the packing, shipping and storing of said vaporizer.

Still another object is to provide effective means for preventing the separation of the receptacle and its lid while the current is on, so as to protect the user a heatin element or receivin a shock.

Wit these and other objects in view our invention consists in the novel construction, arrangement and combination of parts as will be hereinafter more full described, shown and defined in the ap en ed claims.

. Fig. 15 is a top plan view of the modification of Fig. 15. A

Fig. 16 is a side -elevation of a further modification, in which` the deliector is attached to the electric plug.

Referring to the drawings and first vto the construction shown in Figs. 1 to 5, 10 denotes the conventional liquid receptacle, such as a glass jar which may be of square cross section as shown, or other suitable shape. 11 denotes a lid removably mounted thereon, such as by threads. 12 denotes a suitable electric heater consisting 1n this case of a pair of two carbon electrodes 13 carried by metal rods 14 suitably fixed to and insulated from the lid 11 to project therefrom downwardly into the receptacle. The upper ends of said rods 14 project upwardly from the lid and constitute electric terminals 15 for the engagement of an electric plug P or other electric connecting means. 1d denotes a vapor conduit, such as a spout as shown, for the passage of the vapor produced in the receptacle. 17 denotes a support or stand for the receptacle to keep the latter in steady position when in use. This support comprises a base 18 provided with a marginal grippingv flange 19 to sufliciently engage the lower part of the receptacle the position of said means for or jar as to steady its position on said suport. Projecting from and fixed to said base 1n a suitable manner is a vertical post or bary 18 of the support. L

- to vertical side posts 23 Thus far the construction of the device is similarto that described inthe above patents.-

Now, when usinfr a vaporizer of this kind, the patient places the ar as close to his face as possible so that the vapors passing out from the spout can be inhaled through his mouth and' nose. But inasmuch as the vapors tend to disperse in all directions the patient often resorts toa towel or the like covering for his head. and the nozzle to thereby direct the vapors as desired. But the same also strikes other parts of the patients face affecting his eyes and making him feel uncomfortable.

To remedy this drawback we provide a vapor deflector 23. This defie'ctor .is in form' of a scoop or the like and is movably attached fixed to the base so as to be'capable of being positioned to extend over'the s out in the desired direction, and when not 1n use to extend in a vertical position for facilitating packing, shipping and storing of the vaporizer. In the present example a pair of collapsible member 24 are used as attachment means, the same being pivotally attached to each other at 24", to the deflector at one end as at-f24b and to the vertical posts or bars as-at'24c at the other end. In Flg. 1 the defiector is shown in position of use and in Fig. in collapsed position 'for packing or storing purposes.

Another drawback of the hitherto used 'construction is that the separation of recep- 'i deflector itself ma tacle and lid, or the removal of the lid from the receptacle, while the current is on, is vnot positively prevented. In the construction described in the aforenamed patents the holding of the receptacle and lid together is depended upon the member 22 and a loop formed on the rear post 20 of the support and through which the plug is passed when engaging the terminals 15. Owing to the natural or given resiliency of the member 22 and that of the loop the receptacle can when exerting a slight pull in the upward and forward directions be brought into a position where it can be se` arated from or unscrewed from the lid, wit out pulling of the plug, as a result of which the patient is liable .to

`receive a shock or be injured by the exposed electrodes. To do away ,with this drawback -we have provided a locking means whereby under no circumstances could the receptacle and lid be separated while the plug` is. on.

In the example shown in Figs. 1-5 the atthesame time serve as a lock. Here w ile the defieotor extends to'embrace the neck of 5 toward and bears .the support.

23 may be limited by sto s 25 on posts 23i against turning downwar 1y in one direction more than a desired extent, so that they will always be in the (path of the spout when the lid is turned an as long as the lug is in engagement with the terminals. ut when the plug is removed the defiector and link arms 24 can be tilted rearwardly as shown in dotted lines in Fig. 4, which will permit the removal of the lid for filling purposes.

It thus is clear that unless the plug 1s off, the lid will be positively locked in closing position. i,

In Fig. 6 we have shown a modification in which the deflector when moved into the collapsed position is capable of automatically pushing the-plug ofi the terminals. To this end the defiector 23l at its rear edge is provided -with an extension fin er 26 rwhichin gage the lower face of the plug and push the tter off the terminals.

In Figs.v 8 and 9 a modification is shown in which the lifting finger isl not connected with the defiector. I-Iere the rear post 20 has an upper extension to which is hingedly or plvotally attached a manually operable finger 2 the inner end 27 of which extends below the plug andthe other end 27b of which serves as a press finger. As long as the finger 27 is in osition below the plug it prevents the li ing and turning of the receptacle and lid or either of them. But when it is desired to separate the receptacle and lid or remove the latterthe outer end 27 of said linger is depreed, thereby pushing ofl' the plug and simultaneously releasing the lid. The finger nilay be spring actuated (the spring not being s own is shown. Here the handle 28 is not formed on a vertical rear post U-shaped cross piece. The extreme ends of said cross piece are adapted to engage slits 29* in the upper cylindrical ends 29" of vertical side bars or posts 29 fixed to the base of The cross bar vis held in position in said slits by nuts 30 threading on said cylindrical ends 29. The cross handle prevents the separation of receptacle and lid either by its ends 28* bearing tightly on the lidorby being in the and plug or spout when the lidia rotated.

In Fi 11, another modification is shown.

as in Fig. 1 but as a Hereint ere are provided on the l'id 11 straps But if the deflector is collapsi- Vpath of the terminals.

. `in said lid however.

ing is spread a out said de ector.

limit ourselves to the soy mount said deiieetor merely requires or loops 31 into'which prongs or tenons 32 integrally formed with or attached to deilector 23b may be inserted and are adapted to be frictionally retained therein. The delector is thus removably mountable on the lid over the spout 16. l

, In Fig. 12 still another modification is shown. Herein the liquid receptacle is adapted to be mounted in a stand which has a base 33 and uprights 34 (only one of which is shown) at opposite sides o f said base. Prongs or suiporting tongues 35 are pro' vided on the eflector 23 which ma be at# `tached to the respxe'ctive uprights`34 y boltand10.

In 13 still a further modification is disclose Herein, thereismounted on the delector 23 at or near its rear end, a socket 37 having ano ening 38 therein tapered to correspond wit the taper of spout 16. To ushing of socket 37 onto spout 16 until t e are firmly wedged together. Thus this de ector is liliewise removable from over the spout opening.,v v

Figs. 14 and '15 show s'till another modification. Herein, the usual spout is omitted from the lid 11. An o ening 39 is provided ring 40 is provided with afpluralit of downwardly .prongs 41 which latter are ada ted to grip the external side of the lid 11 an' frictionally be retained thereon. Prongs or tenons 42 are provided on a deilectorp23 which are permanently attached to rin 40. In use the latter is mounted on lid lly means of prongs 41 so that opening 39 is covered by deilector 23. Thus va or emergin from said open- The latter removable with its ring 40.

Other modifications are of course,'possible without departing from the principle of 4our invention and `we therefore do not wish ,to
